Options via text input after entity pick:
DE <delta> — extend by delta (negative trims)
TO <total> — set absolute total length / arc length
P <percent> — scale by percentage
<number> — plain number treated as DE delta
Closest end to pick point is modified. Uses CmdResult::LengthenEntity.

Selection-gathering mode: select objects, press Enter to apply.
- Lines: checks collinearity + no-gap, merges into single line span
- Arcs: checks same center/radius + contiguous angles, merges to Arc or Circle
- Uses CmdResult::JoinEntities; geometry computed in cmd_result from document

3-step interactive flow:
1. Entity pick (first break point recorded at click location)
2. Optional first point refinement
3. Second break point → CmdResult::BreakEntity applied in cmd_result
Geometry:
- Line: project p1/p2 onto line parameter space → two line fragments
- Arc: project p1/p2 to arc angles → trim CCW from p1 to p2
- Circle: same as Arc, converts Circle → Arc
- LwPolyline: nearest-vertex split → two polyline fragments

- Deactivate ribbon tool highlight when command ends (issue #1)
- Reset last_point on new command dispatch to fix polar snap offset (issue #2)
- FILLET/CHAMFER: disable text input during entity pick so clicks reach viewport (issue #3)
- Dropdown icon buttons now use RibbonToolClick so they highlight blue when active
- FILLET/CHAMFER: AutoCAD-style sub-step UX — typing R/D + Enter prompts for value
- Fix FILLET arc preview plane: arc was rendering in XZ instead of XY
- Bump version to 0.1.1

Each command implementation is now in the same file as its ribbon
tool definition. Groups moved to a dedicated groups/ toolbar folder.
